My printer is a HP Deskjet F4400 series, bought it March of 2010, and lately it has been making noises. It only happens when I turn it on or when I start printing. The best way to describe it is it is like a loud rattling sound. It lasts only 2-3 seconds, and it's not heard of again until I do another printing, or if I turn it off and then it it on again.
It doesn't affect the prints I make, and I checked inside I don't know if anything is wrong inside (I wouldn't know anyways given my lack of knowledge), it's just this loud sound that lasts a couple of seconds.
Any ideas on what it is? Is there a way to check it on my control panel or something?
